LQ:
look 4 Armourfast kits...
they're 1/72 scale, about 7 parts (upper & lower hull, 2 trax/roadwheel combo pieces, plus a couple of other pieces (mantlet, main gun barrel).
not snaptite, but almost. & they come 2 in the box 4 about $10.
they've got a Sherman. an M10 & a couple of others.
just get some non toxic testors glue (in the blue tube) & have fun !
HTH,
